ルバルブ機構。 In a manual valve mechanism for an outboard motor tilt/trim device that communicates two oil chambers in a cylinder defined by a piston with a tank, the valve block has two oil chambers connected to the tank with a tank port leading to the tank in between. Each oil chamber port leading to two oil chambers is formed, and a manual valve body is rotatably mounted facing the tank port in each flow path connecting the tank port and each oil chamber port, and the manual valve A cam portion is formed in the main body, slide pins that can come into contact with the cam portion are movably disposed in parallel with the manual valve main body, and check valves are provided that are opened and closed by the slide pins. A manual valve mechanism for a tilt/trim device characterized by:
